SPECIFICATION forming part of Letters Patent No. 414,745, dated November 12, 188.9.

Application tiled June 12, 1889. Serial No. .$13,992. (No model.)

To all whom it may concern: 1

le it known that I, TILLIAMWVRIGHR of Vilmington, county of New Castle, State of Delaware, have invented a new and useful Improvement in Rubbing-Irons, of which the following is a true and eXact description, reference being had to th'e accompanying drawings, which form a part of this specification.

Myinvention relates to the construction of the rubbing-irons used with locomotives and railway-cars to prevent shocks between the locomotive and its tender or between two cars, and my object is to enable a close union to be made and maintained between the locomotive and tender, &c.,whether on a straight line or a curve,without interfering with their necessary freedom of motion.

My invention will be best understood after a description of the drawings, in which it is illustrated, and its novel features are hereinafter clearly pointed out in the claims, reference being now had tothe drawings which illustrate my invention, and in which- Figure l shows my improvement applied to a locomotive and to its tender, said locomotive and tender being coupled together and shown as they would stand with respect to each other on a very sharp curve. 2 is a plan view showing my device in its preferred form. Fig. 3 is aview on the sectionline x of Fig. 2. Fig. 4 is a view similar to Fig. 2, the supporting-casting and rubbingiron being sectioned on the line y y of Fig. 3, a special device for actuating the wedge being also shown. Fig. 5 is a view showing a modification of my device, being an enlargement of rubbing-iron attached to the tender in Fig. l, with the rubbing-iron and its supportingcasting shown in section; Fig. 6, a plan for securing the bolt J in the wedge I, as shown. A is a locomotive; B,atender; C, a couplnglink pivoted to each by pins c c.

D and E are rubbingirons, one D made with a long convex face and the other E preferably made, as shown, with a short face to abut against the convex iron D. This difference in form of the rubbing-irons is easily provided for as to locomotives and tenders; but on cars it will be preferable, for obvious reasons of convenience, to have two convex irons abutting against each other.

F and F representcastings to which the rubbing-irons are secured and which may be of any convenient kind, though I prefer to form this casting as is shown by the one marked F, to adapt it for use with my preferred construction.

I will hereinafter refer to the devices on which' the rubbing-irons are supported as buffer-supports.7

I secure the rubbing-irons to the buffersupport in any convenient way which will not interfere with a certain degree of longitudinal motion in the rubbing-iron with respect to the buffer-support, and I provide mechanism for extending the iron to any desired distance from the support. Thus the rubbing-iron may be secured to the buffersupport by right-threaded bolts, as is shown at l I', Fig. 5; but preferably I employ a wedge between the iron and support as affording the iirinest bearing and being at the same time readily adjusted. In practice I have formed the buffer-support F with an inclined face fand projecting flanges f f recessing the flanges along the inclined face to form grooves f2 f2.

' f3 and f4 are pin-holesformec'i in the flanges f f. I form the rubbing-iron D so that it will it between the iianges f j" and give its back an inclination correspond-ing to that of the face of the buffer-support, forming in `it a groove or recess d', with lateral grooves d2 d2. Along its innermost edges d is a slotted pin-hole formed in the center of the iron D, and d3 is a similar slotted pin-hole formed through the flanges which extend along the slot or groove d.

I is the wedge, which I'form with projecting ribs t' z' to iit 4into the grooves f2 f2 and ribs z" t" to fit into the grooves cl2 d2, the wedge itself fitting into the groove d of the rubbing-iron and against the face f of the buffersupport..

3 i4, &c., are pin-holes formed in the wedges I.

G and H are pins by which the device is secured together.

As is shown in the drawings, the rubbingiron D is inserted between the flanges f and secured by the pin G, passing through holes f3 and slot d, the said slot permitting the iron to move to and from the support. I then in- IOC) sert the wedge I in the butter-support and rubbing-iron, its projecting ribs fi and i engaging' with the grooves f2 and (Z2 and binding the buitensupport and rubbing-iron together. (The grooves f2 and (Z2 and the ribs and t" may be single instead of double, as shown; but the double construction is stronger and better.) It is of course obvious that as the wedge I is pushed in the rubbing-iron is thrust outward, and by .inserting the pin II through one ot the holes 2 i i, dsc., and through the slot d3 the rubbing-iron islocked in any desired position.

To make nice adjustments of the rubbingiron, an adjusti110--serew may be used, as.

shown in Fig. 4, where a bolt J is secured in a slot fi of the wedge and its threaded end passed through a standard K, nuts j being secured on the bolt to secure it in place, while permitting any desired change in its position and that of the wedge to which it is attached.

I do not desire to be understood as limiting myself to the exact arrangement shown, except where it is specifically referred to in the claims, the construction I have described as being preferred by me being the best form in which I have embodied my invention, but obviously capable of many modifications without departure from the invention proper involved in it'.

I am aware that buil'crs have been constructed so as to have a longitudinal movement in their supports and provided with springs acting to keep them normally thrust out to the fullest extent, while permitting them to yield under pressure. By my device, however, a close unyielding connection be tween the engine and tender is made practical as distinguished from the yielding eonneetion of such former bulters.

llaving new described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In combination with a butter-support, an extensible rubbing-iron separate from said support and an intervening adjustable wedge orits equivalent, as described, whereby the rubbing-iron can be extended without impairing the rigidity of its connection tothe buffer-support.

f2. In combination with a buiIer-support la', having proj eeting sides f f and a groove or grooves f2, a rubbingiron D, having a curved face, a slot (Z on its back, and a lateral slot or slots Palou g the base ot slot d', and a T-shaped Wedge I, having one or more projecting ribs t' and l, arranged to engage the slots]0g and (Z2, all substantially as specified, and for the purpose of making the rubbing-iron longitudinally extensible.

3. In combination with a buffer-support I", having' projecting sidesff, perforations f and f4, and a groove or grooves f2, a rubbingiron D, having a curved face, a slot (7, on its back, a lateral slot or slots (Z2 along the base of slot d', and slotted periorations cl and d3, and a T-shaped Wedge I, having one or more projecting ribs 't' and i', arranged to engage the slots f2 and d2, and perforations t2 1'5 i, the., arranged to register with the perforationsjI4 and d, and pins G and Il, to connect the parts, all substantially as specified, and

tor the purpose of making the rubbing-iron longitudinally extensible.
